Heretofore safety-pins have been carded by hand by thrusting their pointed ends through a crimped or bowed card and then closing them. Barring crimping and holding the cards, the carding has generally been done by hand. Such machines as have been devised for carding safety-pins have operated on the principle of sticking the pointed crirnped or bowed card.

My invention consists in a safety-pin carding machine designed to insert closed pins in the slots of a slotted card to wiich they are attached'by a locking-strip threaded through. all of them and engaging with one face of the card, the object of my invention being to produce a reliable and eflicient machine largely automatic in its operation, having a large capacity for work, and not liable to be deranged in use.

.Vith these ends in View, my invention consists in a machine for carding safety-pins, ha 'ing certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, twelve streams of closed safety-pins 15, of any approved construction and provided with heads, are fed by'gravity through a gang of inclined chutes 16, the upper ends of which are co-ordin'ated with some source of supply, such, for instance, as a sorting and selecting mechanism by which the pins are fed into the upper ends of'the chutes with their corresponding ends foremost-,- preferably their head-ends, as herein shown.

The lower ends of thesaid inclined chutes 16 register with the upper ends of twelve correspondingly spaced inclined channels 17 traversing the upper face of an inclined delivery-plate 18 mounted on the inclined upper face of thehead 19 of a bracket 20 se-' cured to a bench 21.

The closed pins 15 are discharged by gravity from the lower ends of the said channels 17 into an inclined skeletonized pincarrier unit reciprocating at a right angle to the plane of thesaid channels. As shown, the said carrier comprises a transverselyarranged, notched inner bar 22 and a parallel notched outer bar 23, the space separating these two parallelbars being something less than the length of the pins, whereby the middle portions thereof are'unsupported and exposed. The said bar22 is secured to the upper ends of two plates 24, the lower ends of which are secured to the inner edges of the respective ends of a yoke-piece 25 mounted upon the upper end of a tubular extension 26 reciprocating upona guidepost 27 rigidly mounted at its upper end in the stationary carding-block 28 of the carding-unit. The ends of the outer bar 23 are similarly secured to the upper'ends of two plates 29, the lower ends of which are secured to the-ends of the outer. edge of the coupling-piece 25 aforesaid. The said plates 29' are formed with guide-slots 30receiving bolts 31 entering the carding-block 28, so as to provide for; guiding and steadying the skeletonized pin-carrier in its reciprocating movement at a right angle to the deliveryplate'18 aforesaid. p

The bar 22 aforesaid mounts a plate 32 parallel with it and formed with twelve. spaced notches 83 respectively located in line with the channels 17 and registering with narrower notches 34: formed in the bar 22, these notches 33 and 34: receiving and locat-. ing the coiled ends ofthe pins 15.

The bar. 23 is similarly formed with a series of spaced notches 35 arranged in line separated by a distance slightly wider than the width of the carding-block 28, but not so wide. as the length of the pins, which are thus supported by their ends, rather than by their middle portions. The bar 23 also mounts a stop-plate 86 provided with twelve pockets 37 located in line with the notches 35 but larger than the same and adapted to receive the head-ends of the pins, as shown in Fig. 5, the opposite walls of these notches 87' being beveled, as at 38, to assist in deflecting the pins into their ultimate positions in the pockets 37.. e

The carding-block 28 aforesaid. is inclined to be parallel with the plane in which the pin-carrier reciprocates and formed in its upper edge with twelve transverse clearan'ce-grooves 89 arranged in line with but considerably below the notches 34 and 35 and the pockets 87 of the reciprocating car rie-r unit already described. At their ends, the shallow grooves 39 intersect upstanding bending and deflecting or crimping ribs 40- having rounded outer surfaces and virtually corresponding inlength to the length of the paper card- 41 (Fig. 8). These. ribs also function as guides for the paper lockingstrip- 42 (Fig. 9), forming an. essential part of each card of pins. The block 28 is rigid- 1y secured by screws 48' to a flange 44 up standing from the outer end of the main frame- 20;

To permit the cards 41 to be slid from the left-hand card-tray 45, which is secured to the left-handof the block 28, upon and over the grooved portion thereof, the left-hand plate 24 is formed with a clearance-offset 46, as shown in Figs. 1 and 3, while the lefthand plate 24 is formed with a similar 01iset 47, as shown in the same figures.

The left-hand portion of the cardingblock 28 is formed in its upper face with a shallow recess. 48 for the reception of an adjustable card-stop 49 co-acting with a yielding plunger-stop 50: mounted in the upper end of the right-hand plate 29, and furnished with a spring 51 exerting a constant effort to push the card from right to left against the stop49. The said stops 49 and: 50 provide for the longitudinal positioning of the cards. For their lateral positioning I employ an inner stop 52 (Fig. 1)

I V fastened to the inner face of the cardingblock 28, and a co-acting spring-stop58 projecting from theopen inner edge of a rectangular housing 5'4 secured to a bracket 55- attached to the outer face of the block.

The right-hand end of the carding-block 28 mounts a tray 56 corresponding to the card-tray 45'and designed for thestorage of the locking-strips 42. The tray 45 aforesaid isfurnished withguides 57 and 58 (Fig. 3), which facilitate the feeding of the cards 41 through the clearance offsets 46 and 47 already mentioned.

edge with twelve fingers 6O spaced apart to enter the upper ends of the channels 17 in the delivery-plate 18, while the lower edge of the said gate is formed with twelve corresponding fingers61, similarly entering the channels 17, these two sets of fingers 59 and 61 being sufficiently separated from each other to accommodate, without binding, the full length of a safety-pin. The said gate is furnished. at its ends with downwardly extending parallel arms receiving screw-studs 63 entering the ends of the plate 18 upon which the gate is thus pivoted for rocking movement; The said arms 62 are provided at their lower ends with pawls 64 meeting with teeth 65 upon the upper edges of forwardly inclined roclearms 66 overhanging the plate 18 and respectively secured to the opposite ends of a rock-shaft 67 in the head 19. Springs 68, connecting the arms 66 with the studs on which the pawls 64 are hung, exert a constant effort to swing the gate 59 into its pin-delivering position, as shown in Fig. 5. The outer ends of the arms 66 are connected by a bar-like follower 69, the function of which is to engage with all of the pins of a group of pins after they have been installed in the. skeletonized pin-carrier, so as to steady them and prevent their displacement and also to follow them in their traverse therewith and by its pressure assist in their insertion into the slots 41 of the cards 41.

The said follower 69 is moved for the purpose described, by means of a yoke 70, the ends of which are connected with the respective arms 66' and which is itself con-- nected by a knuckle-joint 71 with the upper end of: a treadle-rod 72,v the lower end of which is attached to a chain 73' running over a pulley 74 and connected at its lower end with a foot-treadle 75 having the usual lifting-spring 76-. V e

A sleeve 77, which for convenience I may call the carrier-actuating sleeve, is loosely mounted upon the upper end of the rod 72 and has sliding bearing at 77 in the frame 20, its upper end co-acting with the lower end of the said knuckle 71, and its lower end resting upon the upper face of an op crating-lever 78 hung in a bracket 79 attached to the frame 20. The outer end of the lever 78 is forked and embraces the tubular extension 26 between two collars 80 shrunk thereupon. For lifting the fol-lower 69 into its elevated. position and, at the same time, restoring the pin-carrier to its elevated position and rocking the gate 59 into its charging position, I employ two springs 81 having their upper ends connected to the The operation of my improved machine is" as follows:

' In the first place, the operator, with her left hand, slides one of the cards 41 from a pile on the tray 45 from left to right,over the grooved portion of the carding-block, so as to position it between the four stops thereof, whereby its slotsil are registered with the transverse clearance-grooves 39 therein. The treadle'75 is now depressed, whereby the rock arms 66 are swung down so as to disengage their teeth from the pawls 64: carried by the gate 59. The springs 68 now act to rock the gate upon its studs 63 into its discharging position in which its fingers 60 enter the upper ends of the channels 17 in the plate 18, while its teeth 61 are lifted from the said channels, whereby the safety-pins previously entered into the gate between the fingers thereof are released and permitted to gravitate downward upon the skeletonized carrier. as indicated in broken lines in Fig. 4, and whereby the teeth 60 hold back the columns ofpins in the chutes 16. The continued depression of the treadle, and consequently the continued downward movement of the arms 66, bring the follower 69 into contact with the upper reaches of all of the pins,'which have now been installed by the action of gravity in the several notches of the carrier, whereby the pins are firmly held against upward displacement therein. The parts are so timed that when the bar 69 makes contact, as described, with the upper reaches of the pins in the carrier, the lower end of the l-znuckle-joint 71 engages with the upper end of the slidable actuating-sleeve 77, the lower end of which now pushes downward upon the lever78, which in turn acts through the tubular extension 26 to draw the loaded carrier downward over the card 41 positioned as described upon the carding-block. The initial downward movement of the carrier v causes its side bars 22 and 23 to engage with the overhanging side edges of the card, whereby the card is crimped, as the ex pression is. over the crimping ribs 40 of the block, its slotted central portion being upwardly bowed, as shown in'Fig. 5, and its -r edges being pressed upon the rear and front faces of the block. The continued downward movement of'the carrier effects theinsertion of the exposed lower reaches of the pins through the slot 41* of the card and into the clearance grooves '89 of the block and therefore in position, as shown in Fig. 5, where they will not interfere with the ready insertion of a locking-strip 42, which the operator now slides from right to left off the strip-pile on the tray 56 and thus threads the strip successively through the pins, themovement of the strip from right 7 toleft being continued until its ends are co-incident with the ends of the card. The strip is now interposed between the back or'under-face of the card and the middle portions or reaches of the pointed ends of' the pins, which portions or reaches are at this time-lying in the bottoms of the transverse clearance-grooves in the carding-block, and the middle portion of the card being arched or upwardly bowed'above them, so -as toprovide free and unobstructed passage for the strip. Pressure upon the treadle 75 now being removed or relieved, the springs 81 promptly' restore the parts of the ma-' chine to the positions in which they appear in Figs; 1 to 4 inclusive, in which they are shown in the positions due them just prior to the beginning of acarding cycle. As the pin-carrier unit is thus lifted away from the carding-block, the tension upon the side edges of the card proper is removed, whereupon the card, ofits own resiliency, resumes approximately its initial flatness, at which time the lower reaches of the pins, acting nearly throughoutthe length of the locking-strip, draw the sameupward into frictional contact with the back of the card, whereby the strip is sufliciently gripped to beheld against accidental longitudinal displacement, but not so firmly but what it may be pulled by one of its ends or the other to release one or-more pins, as may be'desired. When the restoration of parts to their normal positions has been effected and the pin-carrier lifted away from the card ing-block, thecharged card is removed, another card fed in, and the above cycle-of operations repeated. Meanwhile, during the lifting of the pin-carrier, as described, the teeth 65 of the arm 66 have pressed down upon the pawls 64. overcome the tension of the springs 7 5 and rocked the gate 59 for the feeding of another group of twelve pins into it, preparatory to their delivery to the pin-carrier during'the nextsucceeding carding-cycle.
